Regular adult admission at Denver Museum of Nature & Science is $27.95, so timing the visit to the free window keeps $55.90 in a couple's pocket and up to $111.80 for a family of four — each published date. And since this free day is open to everyone, it's the cheapest possible way through the door. The catch is capacity, not money: free slots are reserved in advance and the popular dates go first, so the reservation is the real currency here.
